User input file selection

[Stuart Edwards]

Hi -

This is probably a trivial question, but has me stumped.  I'm writing  
a script that requires the user to input the name of a data file, and  
then load and process the contents.

I tried:

> datafile=input("enter the name of the datafile ", "s")
> load datafile

after inputing the file name, this returns an error 'could not find  
the file datafile'

and

> datafile=input("enter the name of the datafile ", "s")
> load(datafile)

seems to load the name of the datafile as a string and subsequent  
processing merely shuffles the characters in the file name around.   
I've tried various other syntax 'guesses' but no success.

Any suggestions?

Thanks for your time.
